between the british royal family and the papacy have been cordial. this is a very significant gesture of friendship and good will. we are told it is going to be watched by about a billion people on their television screens around the world. >> there is also some controversy surrounding this trip. what is the story there? >> their are small but militant anti-catholic groups in britain. they include the rights people, atheists, people complaining about the cost of the trip, and so on. the child abuse scandal that has beset the catholic church weighs very heavily on the hearts of all catholics, and certainly the pope. that could overshadow the trip to some extent. on the other hand, most people think it is fair that this ancient institution, which has existed for many hundreds of years, has a right also to celebrate the good things it has achieved in those hundreds of years. that is what is going to be doing in the next few days.
